(b) To be visited by a representative of that State.

4. The provisions of paragraph 3 of this article shall be without prejudice to the right of any State Party having a claim to jurisdiction in accordance with article 9, paragraph 1 (b), to invite the International Committee of the Red Cross to communicate with and visit the alleged offender.
